The unit automatically cuts off power when voltage exceeds 140 VAC or drops below 90 VAC. Four LED Status IndicatorsComes with four LED lights that clearly display Normal Voltage, High Voltage, Low Voltage, and Delay Status. These indicators provide a simple and intuitive way to monitor the operating condition of connected appliances. Plug-and-play design ensures easy installation and use. Wide Appliance CompatibilityThis voltage surge protector is suitable for high-power household appliances such as air conditioners, refrigerators, freezers, ice machines, washing machines, and other large electrical equipment.

Built-in Delay ProtectionWhen voltage becomes unstable, the device activates a protection mode and suspends power output. The "DELAY" light will illuminate, and the appliance will restart only after a 3-minute waiting period to ensure the voltage has returned to a safe and stable level. Stable Operating MechanismIn the event of power interruption or abnormal voltage, the surge protector enforces a 3-minute stabilization interval before restoring power. This design helps prevent damage caused by sudden voltage spikes and ensures safe operation of connected devices
